LIQUID MEASURING AND TR ANSFERRING TUBE.

Specification of Letters Patent. Application filed. November 13, 1907'.Serial No. 401,972.

Patented Sept. 15, 1908.

To all whom it may concern:

Be it known that I, ORMSBEE T. FARN- HAM, a citizen of the UnitedStates, residing at the town of East Greenwich, in the county of Kentand State of Rhode Island, have inyented certain new and usefulImprovements 1n Liquid Measuring and Transferring Tubes, of which thefollowing is a specification, reference being hadtherein to theaccompanying drawing.

This invention relates to liquid gages and has for its object to providean extremely simple, neat and effective instrument for picking up,accurately measuring, and readily depositing small quantities of liquid.

An essential feature of this unique instrument is its particularadaptability for measuring medicines in drops, or portions of ateaspoonful. i

It is well known that to pour medicine from a bottle into a spoon toobtain doses of exactly so many dro s requires great care andconsiderable skill? and is a very uncertain method of measuring at thebest. To completely obviate this difficulty and accomplish thismeasuring in a simple and effective manner I have provided a glass tubeadapted to enter the bottle and extend down into the liquid and ick upthe exact amount required. This glass tube may be graduated to indicatea number of drops, drams, teaspoonfuls, or any other convenient unit ofmeasure. I

For measuring medicine the tube is preferably graduated and numbered atone end to indicate drops. VVhena specific number of drops is re uiredthe tube is inserted into the liquid in t e bottle to the de th denotedby the numeral on the gage. he finger of the hand is then laced over theopposite end of the tube thereliy sealing the same and preventing theliquid from running out when the tube is withdrawn. The liquid may thenbe transferred directly to the mouth of the patient and depositedtherein by simply removing the finger from the end of the tube, or whenrequired to be diluted it may be deposited into a glass of water.

The salient features pf the device when used for measuring medicine are,first, its extreme simplicity; second, accuracy in quickly obtaining theexact amount, and third, its perfectly sanitary construction.

The invention is fully set forth in this specification and moreparticularly pointed out inthe appended claims.

In the accom anying drawings: Figure I is a view of the lnstrumentshowing the same held in the hand and inserted through the neck of abottleinto the li uid therein contained, the finger of the hand beingplaced over the opposite end of the tube to seal the same and by'takingadvantage of the atmospheric pressure prevent the liquid from runningout when the tube is withdrawn. Fig. 2shows the instrument after havingremoved the liquid from the bottle in the act of depositing the same bysimply raising the finger and breaking the seal from-the opposite end ofthe tube. Fig. 3\illustrates the instrument as having transferred themedicine in the desired quantity direct from the bottle into thepatients mouth.

Referring to the drawings, the tube shown is transparent and preferablymade of glass,

and has an elongated contracted'portion 1 ada ted to readily pass intothe neck of sma bottles. This reduced portion may be graduated intodrops, teaspoonfuls or any other convenient unit of measure, but formeasuring ,medicine the instrument shown is preferably graduated toindicate drops. The opposite half of this glass tube at 2 is shown asbeing enlarged and adapted to hold a teaspoonful, the same beinggraduated into one, two, three and four'quarters of the capacity of ateaspoon?\ The enlarged portion of this tube is preferably provided witha contracted end at 3 so that the same may be readily covered and sealedby the finger of the hand that holds the tube.

When any portion of a teaspoonful of medicine is required, instead of somany drops, the tube is changed end for end and the large portioninserted into the liquid in the bottle to the depth requiredas indicatedby the numeral on this graduated end. The opposite or small end of thetube is then sealed by placing the finger over the same after which thetube may be withdrawn to deposit the medicine in any desired place.

Another feature of this invention is that when it is desired to takesuch medicines as iron, or the like, that are injurious to the teeth,the same may be carried to the back part of the month by the end of thetube and swallowed without coming into contact with the teeth.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

An instrument of the type described composed'of a glass tube dividedinto two sections, one of said sections being of equal diameterthroughout and formed with a fiat end extremity and being graduated toindicate units of a certain measure, the other section being of greaterand uniform diameter throu hout its major portion and being graduate toindicate units of a different measure than those of the first namedsection, the outer end of said second named section being-contracted andhaving its extremity formed fiat, whereby said sections may be usedinterchangeably and their outer ORMS BEE T. FARNHAM.
